“…Differences between habitats in terms of species richness, number of families, number of trophic groups and frequency of occurrence were assessed by one-way ANOVA (Hector et al 2010). Because heterogeneous landscapes contain multiple habitat types that can vary in community structure, a Venn diagram was used to show assemblage distribution and identify possible overlaps among species in terms of habitat use (Moktefi & Shin 2012).…”

Agricultural landscapes cover approximately 35% of Brazil and are the second greatest threat to biodiversity worldwide. In Brazil, seven millions hectars of land is covered with Eucalyptus plantations, which is considered to have low conservation value. However, studies have shown that heterogeneous silvicultural landscapes, made up of Eucalyptus matrices and patches dedicated to conservation, are able to support a considerable diversity of wild mammals. This study aims to assess the diversity and distribution patterns of medium-tolarge-sized mammals in a silvicultural landscape in Angatuba, São Paulo, Brazil. Nineteen species were detected by camera traps within the study area. Diversity indices did not vary among habitat types (i.e., native vegetation, abandoned pasture and Eucalyptus plantations), suggesting that the species use the landscape as a whole. A relatively diverse range of predator species was found in the area, suggesting that future monitoring programs should focus on predator-prey relationships. A low diversity of frugivores was detected, indicating that management actions should be taken to facilitate their local recovery. Our results stress the fundamental importance of the conservation areas (Permanent Preservation Areas and Legal Reserve) in silvicultural landscapes, as these areas help maintain complexity of the landscape structure.

“…The choice to focus on classes or sets, and whether it is important to make a distinction between them, is one way of choosing whether it is coherent to depict things which may not exist. But this is part of a wider pattern which Moktefi and Shin describe in their survey [31], whereby the "needs and requirements of the logicians who invented the diagrams" continue to change over time and are reflected in the systems they construct.…”

“…Nevertheless, when compared to Euler's circles, with all their limitations, the innovations are in some sense an anti-diagrammatic turn. The new flexibility is influenced in this case at least partly by software engineering, as much as Venn's innovations were influenced by his interest in symbolic, especially Boolean, logic [31]. As Venn diagrams mark the move away from syllogistic reasoning to the increasing complexity of symbolic logic, so the use of circles in spider diagrams mark the new use case for logical diagrams of generalised conceptual modelling.…”

“…Throughout the twentieth century, the success of symbolic logics appeared to reduce the diagrammatic notations of Venn, Peirce and their contemporaries to the status of novelties (see [31] for a survey of the history of diagrammatic logics and the processes that led to this period of relative neglect). Venn and Euler diagrams were valued, as they are today, for their ability to illustrate basic logical concepts to beginners, but not generally as a tool for logicians.…”

Abstract. Spider diagrams are based on Euler and Venn/Peirce diagrams, forming a system which is as expressive as monadic first order logic with equality. Rather than being primarily intended for logicians, spider diagrams were developed at the end of the 1990s in the context of visual modelling and software specification. We examine the original goals of the designers, the ways in which the notation has evolved and its connection with the philosophical origins of the logical diagrams of Euler, Venn and Peirce on which spider diagrams are based. Using Peirce's concepts and classification of signs, we analyse the ways in which different sign types are exploited in the notation. Our hope is that this analysis may be of interest beyond those readers particularly interested in spider diagrams, and act as a case study in deconstructing a simple visual logic. Along the way, we discuss the need for a deeper semiotic engagement in visual modelling.

“…introduction euler diagrams and euler-type diagrams have been an increasingly used and investigated tool for the presentation of logical relations since the late 20 th century (Moktefi & shin, 2012;legg, 2013). euler diagrams are logic diagrams in the form of circles which illustrate the actual relation between concepts or classes.…”

Periods in the Use of Euler-Type Diagrams

Logicians commonly speak in a relatively undifferentiated way about pre-euler diagrams. the thesis of this paper, however, is that there were three periods in the early modern era in which euler-type diagrams (line diagrams as well as circle diagrams) were expansively used. expansive periods are characterized by continuity, and regressive periods by discontinuity: While on the one hand an ongoing awareness of the use of euler-type diagrams occurred within an expansive period, after a subsequent phase of regression the entire knowledge about the systematic application and the history of euler-type diagrams was lost. i will argue that the first expansive period lasted from Vives (1531) to Alsted (1614). the second period began around 1660 with Weigel and ended in 1712 with lange. the third period of expansion started around 1760 with the works of Ploucquet, euler and lambert. Finally, it is shown that euler-type diagrams became popular in the debate about intuition which took place in the 1790s between leibnizians and Kantians. the article is thus limited to the historical periodization between 1530 and 1800.
